Contour plot of irregularly spaced data - Matplotlib
WebThe two options are: Interpolate the data to a regular grid first. This can be done with on-board means, e.g. via LinearTriInterpolator or using external functionality e.g. via scipy.interpolate.griddata. Then plot the interpolated data with the usual contour. Directly use tricontour or tricontourf which will perform a triangulation internally. Web20 apr. 2024 · 2. Surface 3D Plot in MATLAB. A surface plot is somewhat similar to a mesh plot.
